Ask HN: developer resources for your favorite SAAS services ?

To make it easier to build apps on top of SAAS services, we're starting to gather developer resources on http://kingapi.com (eg: http://kingapi.com/details/madmimi). The idea here is to help people selecting a service by linking to resources that show how someone already used it, technically. So we'll focus on third-parties how-to's mostly, such as blog posts, screencasts, more than company provided content (although this is still interesting, but we'd like to avoid "duplicating" the service website). We'll fill this ourselves (Sébastien Gruhier and me) but if anyone wants to help, we welcome suggestions warmly :) (either here or directly on the site). Thanks for your help.
